• #### A Local Streamline Eulerian-Lagrangian Method for Two-Phase Flow ﻿

(Journal article, 2000)
A method for solving the saturation equation for two-phase now is presented. The method may be viewed as an operator splitting method or as an Eulerian-Lagrangian backtracking procedure or as a modi£ed method of characteristics. ...
• #### Modeling of Multi Phase Flow in Porous Media: Operator Splitting, Front Tracking, Interfacial Area and Network Models ﻿

(Doctoral thesis, 2001-12-20)
In this work several new numerical methods and a new mathematical model related to multi phase flow in oil reservoirs have been developed, implemented and tested. The numerical difficulties in multi phase flow stem from ...
• #### On Solving a Three Phase Flow Model with Capillary Forces ﻿

(Master thesis, 1998-07-10)
• #### Operator splitting methods for systems of convection-diffusion equations: nonlinear error mechanisms and correction strategies ﻿

(Peer reviewed; Journal article, 2001)
Many numerical methods for systems of convection-diffusion equations are based upon an operator splitting formulation, where convective and diffusive forces are accounted for in separate substeps. We describe the nonlinear ...
• #### A pore network model for calculation of interfacial velocities ﻿

(Peer reviewed; Journal article, 2003)
Two-phase flow in porous media is characterized by fluid-fluid interfaces that separate the fluid phases at the pore scale. These interfaces support pressure differences between phases, and their dynamics allow for saturation ...
• #### A Streamline Front Tracking Method for Two- and Three-Phase Flow Including Capillary Forces ﻿

(Contemporary Mathematics; 295, Chapter, 2002)
• #### Two phase flow including interfacial area as a variable ﻿

(Journal article, 2000)
Based on the procedure of (Gray & Hassanizadeh 1998) we state macroscale conservation equations for multi phase flow in porous media including interfacial area as a variable. The phases we consider are a solid phase, a ...
